If you enjoy the television series Blacklist and black-ops stories you will enjoy this surprise offering from Twilight author Stephenie Meyer.
The Chemist is a former black ops government employee known for her ability to use various drugs, poisons and their antidotes to chemically torture people with information the government needs. However, "The Chemist" has been on the run since discovering that those in charge are perhaps operating by their own agenda and survival depends on disappearing. Once you get past the initial few chapters the story takes off and doesn't let up until the final scene. Full of clandestine government operations, treachery, back-stabbing, bio-terriorism plots, chemical torture, and run-for-your life danger. This book has it all. A great read, you won't want to put down.
